Air Handler Components

Air Handler Components. This article will take different types of air handlers and disassemble them part by part. This will give you a good description of each part and hopefully a better understanding of the air handler. Most of the components associated with the air handler are in the air handler. However, there are a few components which are not in the air handler but associated with the air handler.

There are some hot water and cold water coils which are not fixed in the air handler. They are downstream in the ductwork. There are also some gas and electric duct heaters which are mounted in the ductwork. They are completely reliant on the air handler for air flow. These systems will also be covered. Hopefully, this article will offer you a comprehensive look at the air handler, all its parts, and how it functions. (more…)

Caution is always advised around mechanical and electrical equipment including the air handler. Turn the power off before removing any panels.

Air HandlersAir Handlers - An air handler is usually located in the garage, a closet, or in the attic (unless you have a package unit then the air handler is incorporated into one system). It is essential to any AC unit and heating forced air system. All AC units need an air handler or way to move air. It can be a part of your furnace and houses the evaporator coils, the blower motor, and some HVAC controls. It can be an up-flow, downflow, or horizontal flow AHU (air handling unit). (more…)

Attic Installation Horizontal Flow Air Handler | HVAC Airflow

Attic Installation Horizontal Flow Air Handler – Attic Air Handler – AHUThis is a horizontal flow air handler installed in the attic. Notice the drain pan under the air handling unit to catch condensation if the primary pan were to overflow. This is the secondary condensation pan which is installed under the air handler to save a ceiling.

Also slightly visible is a float switch which offers triple protection against flooding in an attic if the primary drain were to plug up. The primary and secondary drains coming from the air handler also drain into condensation pumps. These pumps have floats inside them and a reservoir. (more…)
